What is a mill rate? It's the amount of property tax payable per $1,000 of assessed value. A rate of 6.18 mills means $6.18 in tax for every $1,000 your property is assessed at — so a $500,000 home pays roughly $3,090/year. Use the % Rate / Mill Rate toggle above the table to switch between formats — they show the same number expressed differently.

A plain English guide to Alberta's assessment appeal process — deadlines, grounds, evidence, and what to expect. Written by a property tax analyst.
In Alberta, every property is assigned an assessed value each year by the municipality. That value is used to calculate your property tax bill. If you believe your assessed value is incorrect — either too high compared to similar properties, or based on inaccurate information — you have the right to appeal it.
A successful appeal can lower your assessed value, which directly reduces your tax bill — not just for the current year, but potentially for future years if the correction carries forward. For commercial properties, even a modest reduction in assessed value can translate to thousands of dollars in annual savings.
Important distinction
You can only appeal your assessed value — not the mill rate itself. The mill rate is set by your municipality and is not subject to individual appeal. If your assessed value is fair but the mill rate feels high, that's a political question for your council, not an appeal process.
Not every disagreement with your assessment qualifies. Alberta's Municipal Government Act sets out specific grounds on which an appeal can succeed. The strongest grounds are:
Your assessed value is materially higher than similar properties in your neighbourhood — same size, age, condition, and location. This is the most common and most winnable ground.
The municipality has wrong information — incorrect square footage, wrong year built, listing a finished basement you don't have, or missing a functional obsolescence like a structural issue or difficult access.
Alberta assessments are supposed to reflect market value as of July 1 of the prior year. If your assessed value is significantly above what you could reasonably sell for, that's a valid ground — especially in a declining market.
Your property has been classified as non-residential when it should be residential, or is carrying a subclass that doesn't apply. Classification errors are less common but can have a large tax impact given Alberta's significant residential/non-residential rate gap.
What won't work: "My taxes are too high," "I can't afford this," or "other cities have lower rates." These are not valid appeal grounds under the MGA. The appeal board can only consider whether your assessed value is correct — not whether the tax rate is fair.
Missing the deadline means losing your right to appeal for that year — there are no extensions. The Alberta assessment appeal timeline works as follows:
Calgary note
Calgary's Customer Review Period typically runs January through March. Contacting the assessor during this period — before filing a formal complaint — can sometimes resolve issues without a hearing. Always try the informal route first.
The burden of proof is on you as the appellant. The assessor's value is presumed correct until you demonstrate otherwise. Strong appeals are evidence-based — not just assertions that you think the value is too high.
When your notice arrives in January, check the assessed value, property class, and listed characteristics. Note the appeal deadline — it's printed on the notice. Request your full assessment record from the municipality if you want to see the detail behind the number.
Before filing a formal complaint, call or visit the assessor's office. Explain what you believe is incorrect. Many assessment errors — wrong square footage, incorrect year, missing deductions — get corrected at this stage without needing a formal hearing. This costs nothing and is always worth trying.
If the informal route doesn't resolve it, file a formal complaint before the deadline. In Calgary this is done through the Composite Assessment Review Board (CARB). In other municipalities it's the local ARB. There is a filing fee — typically $50 for residential, higher for commercial — which is refunded if your appeal succeeds.
Gather your comparables, property records, photos, and any expert opinions. Organize them clearly. The board will expect you to present a coherent argument — not just a complaint. Submit your evidence package to the board and the assessor before the hearing date.
Hearings are typically 30–60 minutes. You'll present your case, the assessor will respond, and board members may ask questions. You don't need a lawyer — many property owners self-represent successfully for residential appeals. For complex commercial appeals, professional representation is worth considering.
The board issues a written decision, typically within a few weeks of the hearing. If successful, your assessment is amended and your tax bill adjusted accordingly. If unsuccessful, you can appeal further to the Court of Queen's Bench — though this is rare and typically only worthwhile for very large commercial disputes.
Commercial property appeals follow the same basic process but are typically more complex and higher stakes. A few things worth knowing:
No. The board can only reduce or maintain your assessment — it cannot increase it as a result of your appeal. There is no downside risk to filing a well-founded appeal.
Yes. You must pay your tax bill by the due date regardless of your appeal status. If your appeal succeeds, you will receive a refund or credit for the difference.
The filing fee for a residential complaint is typically around $50 in most Alberta municipalities and is refunded if you win. Commercial filing fees are higher. There is no cost for the informal stage.
Yes. A new assessment is issued each year and you have the right to appeal each one independently. If your assessment continues to seem high, appealing annually is reasonable.
Typically four to six months from the time you file to the time you receive a decision. Hearings are usually scheduled for spring or early summer.
For residential appeals, many homeowners self-represent successfully. For commercial properties or where the assessment gap is large, a property tax consultant adds significant value and typically works on contingency.

Property tax data in Canada is scattered across hundreds of municipal websites, provincial portals, and assessment authorities — each using different classification systems, codes, and formats. Alberta uses MGA Classes. BC Assessment uses numbered Classes 1 through 9. Ontario uses MPAC's RTC code system with dozens of subclasses. None of it is in one place.
MillRate.ca consolidates all of it.

For deeper analysis we offer Alberta property tax insight reports — property-specific PDFs covering assessed value benchmarking, historical trends, neighbourhood comparisons, and a professional Tax Risk Rating.
